Their sound signature is somewhat darker and less transparent than that of the Worktunes Connect + AM/FM but I quite like it. This helps reduce echoes and protects your hearing, which is especially helpful if you’re switching between indoor and outdoor shooting ranges. I purchased all Bluetooth earmuffs reviewed here at standard retailers and put them through some good testing. The ISOtunes FREE’s dual omnidirectional microphones have CVC background noise canceling technology.

You can also use the Walker’s Link app (on iOS and Android) to monitor battery levels and set program settings.This works OK in a quiet environment, but the louder the environment, the more disturbing this “hear-through-function” gets. Operation: a micro USB charging port in one of the earmuffs connects with the included USB charging cord; a charger is not included.

These earplugs are essential for heavy-duty tasks in industrial settings like construction sites or factories. Furthermore, the addition of Bluetooth introduces even more things to think about, like connection quality and stability. Depending on the situation, you can turn up the media input volume while lowering the ambient noise level and vice versa. With these earmuffs, you can choose between a wireless Bluetooth connection or a standard stereo headphone cable.This collection of products are fully certified to meet these standards and are limited to 79 dB for use in professional and semi-professional environments.

The Sync Stereo’s volume limiter seems to rely solely on the output of your device not exceeding a certain volume, so you have to exercise caution and be sensible! Some muffs are just Bluetooth capable, whilst others combine Bluetooth with AM/FM or FM only radios.Unfortunately, like with the Sync Wireless, the headband of the Howard Leight Sync Stereo doesn’t fit large heads. The battery life varies depending on the model and usage, but most Bluetooth Ear Defenders offer several hours of continuous playback and talk time on a single charge. Even when performing strenuous and fast-paced activities, the earbuds will remain securely in place. Ideally suited for use in DIY, lawn mowing, or taking the boredom away for wearing earmuffs for long periods at work.
